The Spanish capital, Madrid, is yet another lovely city to jet off for the weekend, and flights to and from Madrid Barajas Airport are usually fairly inexpensive. Spend an afternoon getting lost in the ever-charming Retiro Park, home to the gorgeous Crystal Palace (which may or may not inspire you to jump around singing, "Sixteen Going on Seventeen").
Oh, and don't forget to indulge in a night of drinks and dancing Teatro Kapital Madrid — the city's largest club, with a whopping seven floors and the chance to party to virtually any genre of music, from Latin to House.
